Abstract

The present invention relates to a method for determining the authenticity of an object, the method comprising the step of: providing anthentication code, determining the positions of particles being distributed in an object, encoding of the positions to provide a check-code, using the check-code and the authentication-code to determine the authenticity of the object. A generator polynomial, a step of determining if the particles are distributed in a three-dimensional pattern, or photodetectors with different angles, can be used. <IMAGE>
